ever allowed your printer to update over the internet? chances are that same serial number attached to the printer, which is now encoded into your document, is now attached to an IP that can be meaningfully time/date attached to your e.g. cable modem MAC address which is attached to the location of the printer - at your house/work/etc… and thats just one publically known mechanism. if your printer is attached to a network with internet access, are you sure its never pinged the manufacturer? are you suresure?
never underestimate the trail of digital forensics you leave behind when there is a sufficiently motivated adversary. seriously evaluate your risks and harm exposure and plan accordingly. just sayin’
